An entrepreneur who was warned by a doctor that he was in dangerously poor health is launching a company that will help customers get back on track with a personalized nutrition plan. The $299 plan includes a blood test – you have to draw your own blood at home and mail it in – then analysis of 60 biomarkers, including amino acids, vitamin levels, blood sugar, and some genetic variants. The genetic information suggests how you may respond to diet. A metabolic rate "challenge" involves drinking a special milkshake and sending in more blood to determine response to fats, carbs and sugars. Lastly, the company provides a 30-minute consultation with a registered dietitian who offers nutrition advice (but not disease diagnosis).
